"Earlier this week Apple released updated Mac Pros that use Intel's new Penryn processors. Also new is the fact that the standard Mac Pro configuration now comes with eight (instead of four) cores. Of course, what I've been wondering (as I sit here and think about getting a new Mac Pro) is how does the new standard eight-core Mac Pro perform compared to the old high-end Mac Pro? I've gathered Geekbench 2 results for both Mac Pros to find out."
